Your Brain’s Memory Back-Up System

Strong memories involve groups or teams or networks of neurons that fire together. Neuroscientists have long said that “neurons that fire together wire together.” Recently, research at Cal Tech has shown how repeated exposure to something recruits multiple neurons into the memory system, creating built-in redundancy. This means that when trying to retrieve a memory, it is easier because there are more neural pathways to connect to it. This further reinforces research that multi-sensory exposure and practice helps create stronger and more enduring memory that is subsequently easier to retrieve.
